Subset and superset checks in Python - Mini Project: Build & Apply

Subset and Superset Checks

📖 Scenario: You are organizing a small book club. You have a list of books that the club owns and a list of books a member owns. You want to check if the member's books are all part of the club's collection or if the club's collection is fully included in the member's books.

🎯 Goal: Build a program that checks if one set of books is a subset or superset of another set.

📋 What You'll Learn

Create two sets of books with exact titles

Create a variable to hold the member's book set

Use subset and superset checks with the correct set methods

Print the results clearly

💡 Why This Matters

🌍 Real World

Checking subsets and supersets is useful when comparing collections, like checking if a user's permissions are included in a system's allowed permissions.

💼 Career

Understanding set relationships helps in data filtering, access control, and managing groups in software development and data analysis jobs.

1

Create the book sets

Create a set called club_books with these exact book titles: 'Pride and Prejudice', '1984', 'To Kill a Mockingbird', 'The Great Gatsby'.

Python

# Create the set club_books with the given book titles
# Your code here

Need a hint?

Use curly braces {} to create a set with the exact book titles inside quotes.

2

Create the member's book set

Create a set called member_books with these exact book titles: '1984', 'The Great Gatsby'.

Python

club_books = {'Pride and Prejudice', '1984', 'To Kill a Mockingbird', 'The Great Gatsby'}
# Create the set member_books with the given book titles
# Your code here

Need a hint?

Use curly braces {} to create the set with the exact book titles inside quotes.

3

Check subset and superset

Use the set methods issubset() and issuperset() to create two variables: is_subset to check if member_books is a subset of club_books, and is_superset to check if club_books is a superset of member_books.

Python

club_books = {'Pride and Prejudice', '1984', 'To Kill a Mockingbird', 'The Great Gatsby'}
member_books = {'1984', 'The Great Gatsby'}
# Create is_subset and is_superset using issubset() and issuperset()
# Your code here

Need a hint?

Use variable = set1.issubset(set2) and variable = set1.issuperset(set2) to check the relationships.

4

Print the results

Print the values of is_subset and is_superset with clear messages using print().

Python

club_books = {'Pride and Prejudice', '1984', 'To Kill a Mockingbird', 'The Great Gatsby'}
member_books = {'1984', 'The Great Gatsby'}
is_subset = member_books.issubset(club_books)
is_superset = club_books.issuperset(member_books)
# Print the results with clear messages
# Your code here

Need a hint?

Use print(f"message {variable}") to show the results clearly.
